3% polidocanol foam sclerotherapy versus hemorrhoidal artery ligation with recto anal repair in hemorrhoidal disease grades II-III: a randomized, pilot trial.

PURPOSE: Polidocanol foam sclerotherapy (SP) versus doppler-guided hemorrhoidal artery ligation with recto-anal repair (HAL-RAR) in the treatment of hemorrhoidal disease (HD) was analyzed. METHODS: A prospective, randomized study including patients with HD grades II and III was performed. Participants were randomly assigned (1:1) into SP or HAL-RAR, during a recruitment period between September 2019 and February 2020. Therapeutic success (Sodergren's and bleeding scores) was the primary outcome. Other outcomes evaluated included complications and implication in the professional life. Efficacy and safety outcomes were evaluated during the 8 weeks after surgery or the final SP session. RESULTS: Forty-six patients were allocated either to SP (n=22) or HAL-RAR (n=24). Most patients achieved therapeutic success (SP 100% vs. HAL-RAR 90.9%, p=0.131). Complete success was higher in the SP group (91.7% vs. 68.2%, p=0.045) and SP patients had less complications (25% vs. 68.2%, p=0.003). HAL-RAR had a greater negative impact on work activity of the patient. CONCLUSION: SP was more effective and safer than HAL-RAR. SP patients had less impact on their work activity.

Polidocanol Foam Sclerotherapy Versus Rubber Band Ligation in Hemorrhoidal Disease Grades I/II/III: Randomized Trial.

BACKGROUND: Rubber band ligation and sclerotherapy are considered the office-based procedures of choice in hemorrhoidal disease. However, there are no studies comparing rubber band ligation and polidocanol foam sclerotherapy. OBJECTIVE: We aimed to evaluate the efficacy and safety of polidocanol foam sclerotherapy compared with rubber band ligation. DESIGN: This study was a randomized open-label study with 1-year follow-up. SETTINGS: The study was conducted in the colorectal unit of a tertiary hospital. PATIENTS: One hundred twenty patients with hemorrhoidal disease grades I to III were included. INTERVENTIONS: Patients were stratified by hemorrhoidal disease grade and randomly assigned (1:1) to treatment with either rubber band ligation (n = 60) or polidocanol foam sclerotherapy (n = 60). MAIN OUTCOME MEASURES: Efficacy outcomes included therapeutic success and recurrence. Safety outcomes included the occurrence of complications related to the procedures. RESULTS: Therapeutic success was not significantly different between the groups (polidocanol foam sclerotherapy 93.3% vs rubber band ligation 85.0%, p = 0.14). However, complete success rate was higher in the polidocanol foam sclerotherapy group (88.3% vs 66.7%, p = 0.009) with fewer office-based sessions (mean ± SD: 1.32 ± 0.60 vs 1.62 ± 0.76, p = 0.02). Recurrence rates were lower in the polidocanol foam sclerotherapy group (16.1% vs 41.2%, p = 0.004). Most recurrences were mild (83.3%). Complications were more frequent in the rubber band ligation group (30.0% vs 10.0%, p = 0.01) and were mostly minor (91.7%). No severe complications were observed in either group. LIMITATIONS: This study was performed in a single center, and both patients and investigators were not blinded to the treatment group. CONCLUSIONS: Both procedures are effective in the treatment of hemorrhoidal disease grades I to III. Polidocanol foam sclerotherapy was more effective than rubber band ligation when considering complete success. Patients in the polidocanol foam sclerotherapy group needed fewer treatment sessions, had lower recurrence rates, and were less likely to have complications.

ESCLEROTERAPIA CON ESPUMA DE POLIDOCANOL VERSUS LIGADURA CON BANDA DE GOMA EN LOS GRADOS I / II / III DE ENFERMEDAD HEMORROIDAL ENSAYO ALEATORIZADO: ANTECEDENTES:La ligadura con banda elástica y la escleroterapia se consideran los procedimientos de elección en el consultorio para la enfermedad hemorroidal. Sin embargo, no hay estudios que comparen la ligadura con bandas elastica y la escleroterapia con espuma de polidocanol.OBJETIVO:Nuestro objetivo fue evaluar la eficacia y seguridad de la escleroterapia con espuma de polidocanol en comparación con la ligadura con bandas elastica.DISEÑO:Estudio aleatorizado randomizado, abierto, con seguimiento de 1 año.AJUSTES:El estudio se realizó en una unidad colorrectal de un hospital terciario.PACIENTES:Se incluyeron 120 pacientes con enfermedad hemorroidal grados I a III.INTERVENCIONES:Los pacientes fueron estratificados por grado de enfermedad hemorroidal y asignados al azar (1: 1) al tratamiento con ligadura con banda elastica (n = 60) o escleroterapia con espuma de polidocanol (n = 60).PRINCIPALES MEDIDAS DE RESULTADO:Los resultados de eficacia incluyeron el éxito terapéutico y la recurrencia. Los resultados de seguridad incluyeron la aparición de complicaciones relacionadas con los procedimientos.RESULTADOS:El éxito terapéutico no fue significativamente diferente entre los grupos (escleroterapia con espuma de polidocanol 93,3% vs ligadura con banda de goma 85,0%, p = 0,14). Sin embargo, la tasa de éxito completo fue mayor en el grupo de escleroterapia con espuma de polidocanol (88,3% vs 66,7%, p = 0,009), con menos sesiones en el consultorio (media ± desviación estándar: 1,32 ± 0,60 vs 1,62 ± 0,76, p = 0,02). Las tasas de recurrencia fueron más bajas en el grupo de escleroterapia con espuma de polidocanol (16,1% vs 41,2%, p = 0,004). La mayoría de las recurrencias fueron leves (83,3%). Las complicaciones fueron más frecuentes en el grupo de ligadura con bandas elastica (30,0% vs 10,0%, p = 0,01) y fueron en su mayoría menores (91,7%). No se observaron complicaciones graves en ninguno de los grupos.LIMITACIONES:Este estudio se realizó en un solo centro y ni los pacientes ni los investigadores estaban cegados al grupo de tratamiento.CONCLUSIONES:Ambos procedimientos son efectivos en el tratamiento de la enfermedad hemorroidal grados I a III. La escleroterapia con espuma de polidocanol fue más eficaz que la ligadura con banda de goma cuando se consideró el éxito completo. Los pacientes del grupo de escleroterapia con espuma de polidocanol necesitaron menos sesiones de tratamiento, tuvieron tasas de recurrencia más bajas y menos probabilidades de tener complicaciones.

Dysregulation of T cell receptor N-glycosylation: a molecular mechanism involved in ulcerative colitis.

The incidence of inflammatory bowel disease is increasing worldwide and the underlying molecular mechanisms are far from being fully elucidated. Herein, we evaluated the role of N-glycosylation dysregulation in T cells as a key mechanism in the ulcerative colitis (UC) pathogenesis. The evaluation of the branched N-glycosylation levels and profile of intestinal T cell receptor (TCR) were assessed in colonic biopsies from UC patients and healthy controls. Expression alterations of the glycosyltransferase gene MGAT5 were also evaluated. We demonstrated that UC patients exhibit a dysregulation of TCR branched N-glycosylation on lamina propria T lymphocytes. Patients with severe UC showed the most pronounced defect on N-glycan branching in T cells. Moreover, UC patients showed a significant reduction of MGAT5 gene transcription in T lymphocytes. In this study, we disclose for the first time that a deficiency in branched N-glycosylation on TCR due to a reduced MGAT5 gene expression is a new molecular mechanism underlying UC pathogenesis, being a potential novel biomarker with promising clinical and therapeutic applications.

Antiplatelet agents and/or anticoagulants are not associated with worse outcome following nonvariceal upper gastrointestinal bleeding.

BACKGROUND: Nonvariceal upper gastrointestinal bleeding emerges as a major complication of using antiplatelet agents and/or anticoagulants and represents a clinical challenge in patients undergoing these therapies. AIM: To characterize patients with nonvariceal upper gastrointestinal bleeding related to antithrombotics and their management, and to determine clinical predictors of adverse outcomes. METHODS: Retrospective cohort of adults who underwent upper gastrointestinal endoscopy after nonvariceal upper gastrointestinal bleeding from 2010 to 2012. The outcomes were compared between patients exposed and not exposed to antithrombotics. RESULTS: Five hundred and forty-eight patients with nonvariceal upper gastrointestinal bleeding (67% men; mean age 66.5 ± 16.4 years) were included, of which 43% received antithrombotics. Most patients had comorbidities. Peptic ulcer was the main diagnosis and endoscopic therapy was performed in 46% of cases. The 30-day mortality rate was 7.7% (n = 42), and 36% were bleeding-related. The recurrence rate was 9% and 14% of patients with initial endoscopic treatment needed endoscopic retreatment. There were no significant differences between the exposed and non-exposed groups in most outcomes. Co-morbidities, hemodynamic instability, high Rockall score, low hemoglobin (7.76 ± 2.72 g/dL) and higher international normalized ratio (1.63 ± 1.13) were associated significantly with mortality in a univariate analysis. CONCLUSIONS: Adverse outcomes were not associated with antithrombotic use. The management of nonvariceal upper gastrointestinal bleeding constitutes a challenge to clinical performance optimization and clinical cooperation.

Diagnosis and management of nonvariceal upper gastrointestinal hemorrhage: European Society of Gastrointestinal Endoscopy (ESGE) Guideline.

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the diagnosis and management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). Main Recommendations MR1. ESGE recommends immediate assessment of hemodynamic status in patients who present with acute upper gastrointestinal hemorrhage (UGIH), with prompt intravascular volume replacement initially using crystalloid fluids if hemodynamic instability exists (strong recommendation, moderate quality evidence). MR2. ESGE recommends a restrictive red blood cell transfusion strategy that aims for a target hemoglobin between 7 g/dL and 9 g/dL. A higher target hemoglobin should be considered in patients with significant co-morbidity (e. g., ischemic cardiovascular disease) (strong recommendation, moderate quality evidence). MR3. ESGE recommends the use of the Glasgow-Blatchford Score (GBS) for pre-endoscopy risk stratification. Outpatients determined to be at very low risk, based upon a GBS score of 0 - 1, do not require early endoscopy nor hospital admission. Discharged patients should be informed of the risk of recurrent bleeding and be advised to maintain contact with the discharging hospital (strong recommendation, moderate quality evidence). MR4. ESGE recommends initiating high dose intravenous proton pump inhibitors (PPI), intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour), in patients presenting with acute UGIH awaiting upper endoscopy. However, PPI infusion should not delay the performance of early endoscopy (strong recommendation, high quality evidence). MR5. ESGE does not recommend the routine use of nasogastric or orogastric aspiration/lavage in patients presenting with acute UGIH (strong recommendation, moderate quality evidence). MR6. ESGE recommends intravenous erythromycin (single dose, 250 mg given 30 - 120 minutes prior to upper gastrointestinal [GI] endoscopy) in patients with clinically severe or ongoing active UGIH. In selected patients, pre-endoscopic infusion of erythromycin significantly improves endoscopic visualization, reduces the need for second-look endoscopy, decreases the number of units of blood transfused, and reduces duration of hospital stay (strong recommendation, high quality evidence). MR7. Following hemodynamic resuscitation, ESGE recommends early (≤ 24 hours) upper GI endoscopy. Very early (< 12 hours) upper GI endoscopy may be considered in patients with high risk clinical features, namely: hemodynamic instability (tachycardia, hypotension) that persists despite ongoing attempts at volume resuscitation; in-hospital bloody emesis/nasogastric aspirate; or contraindication to the interruption of anticoagulation (strong recommendation, moderate quality evidence). MR8. ESGE recommends that peptic ulcers with spurting or oozing bleeding (Forrest classification Ia and Ib, respectively) or with a nonbleeding visible vessel (Forrest classification IIa) receive endoscopic hemostasis because these lesions are at high risk for persistent bleeding or rebleeding (strong recommendation, high quality evidence). MR9. ESGE recommends that peptic ulcers with an adherent clot (Forrest classification IIb) be considered for endoscopic clot removal. Once the clot is removed, any identified underlying active bleeding (Forrest classification Ia or Ib) or nonbleeding visible vessel (Forrest classification IIa) should receive endoscopic hemostasis (weak recommendation, moderate quality evidence). MR10. In patients with peptic ulcers having a flat pigmented spot (Forrest classification IIc) or clean base (Forrest classification III), ESGE does not recommend endoscopic hemostasis as these stigmata present a low risk of recurrent bleeding. In selected clinical settings, these patients may be discharged to home on standard PPI therapy, e. g., oral PPI once-daily (strong recommendation, moderate quality evidence). MR11. ESGE recommends that epinephrine injection therapy not be used as endoscopic monotherapy. If used, it should be combined with a second endoscopic hemostasis modality (strong recommendation, high quality evidence). MR12. ESGE recommends PPI therapy for patients who receive endoscopic hemostasis and for patients with adherent clot not receiving endoscopic hemostasis. PPI therapy should be high dose and administered as an intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour) for 72 hours post endoscopy (strong recommendation, high quality evidence). MR13. ESGE does not recommend routine second-look endoscopy as part of the management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). However, in patients with clinical evidence of rebleeding following successful initial endoscopic hemostasis, ESGE recommends repeat upper endoscopy with hemostasis if indicated. In the case of failure of this second attempt at hemostasis, transcatheter angiographic embolization (TAE) or surgery should be considered (strong recommendation, high quality evidence). MR14. In patients with NVUGIH secondary to peptic ulcer, ESGE recommends investigating for the presence of Helicobacter pylori in the acute setting with initiation of appropriate antibiotic therapy when H. pylori is detected. Re-testing for H. pylori should be performed in those patients with a negative test in the acute setting. Documentation of successful H. pylori eradication is recommended (strong recommendation, high quality evidence). MR15. In patients receiving low dose aspirin for secondary cardiovascular prophylaxis who develop peptic ulcer bleeding, ESGE recommends aspirin be resumed immediately following index endoscopy if the risk of rebleeding is low (e. g., FIIc, FIII). In patients with high risk peptic ulcer (FIa, FIb, FIIa, FIIb), early reintroduction of aspirin by day 3 after index endoscopy is recommended, provided that adequate hemostasis has been established (strong recommendation, moderate quality evidence).

Out-of-hours endoscopy for non-variceal upper gastrointestinal bleeding.

BACKGROUND: Most countries lack a well-coordinated approach to out-of-hours endoscopy. Economic constraints and lack of resources have been identified as important barriers. OBJECTIVE: To assess the performance evaluation of an out-of-hours emergency endoscopy model of care. DESIGN: During a 3 year period (January 2010 to December 2012), data from consecutive outpatients (n = 332) with non-variceal acute upper gastrointestinal bleeding admitted or transferred to a single referral hospital were prospectively collected. RESULTS: 34% (n = 113) were direct admissions whereas 66% (n = 219) were transferred from other hospitals. Median time to upper endoscopy esophagogastroduodenoscopy (EGD) was 6 h and 7.7 h for direct admissions and transferred, respectively. EGD was performed within 24 h in 90% of the patients. Rebleeding, in-hospital mortality, 30 day mortality and need for surgery were respectively 9.8%, 5.8%, 7.4%, and 6.6% and were not significantly different between the two groups. Age, malignancy, and moderate to high clinical Rockall risk score were independent predictors of in-hospital mortality in both groups. Age remained as an important predictor of main outcomes in transferred patients, while comorbidities differed according to admission status and predictable outcomes. CONCLUSION: This gastroenterology emergency model improved access and equity to out-of-hours endoscopy in an effective, safe, and timely way, recognized by the rates and the homogeneity observed in the outcomes, between transferred patients and direct admissions.

Office-Based Procedures in the Management of Hemorrhoidal Disease: Rubber Band Ligation versus Sclerotherapy - Systematic Review and Meta-Analysis.

Introduction: The most frequently used office-based procedures in hemorrhoidal disease (HD) are rubber band ligation (RBL) and sclerotherapy. Few studies have been published comparing the various types of instrumental therapy. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of sclerotherapy and RBL. Methods: Three online databases were searched. Efficacy (control of symptoms, prolapse, bleeding and pain, patients' satisfaction, and disease recurrence) and safety (complications, such as pain and bleeding) were the assessed outcomes. Pooled relative risks (RR) were computed for each outcome using a random-effects model, and heterogeneity was assessed by Cochran's Q test and I2. Results: Six RCTs and three cohort studies were included. Control of prolapse and bleeding was significantly higher with RBL (93.1% RBL vs. 66.4% sclerotherapy, RR 1.34, 95% CI 1.12-1.60 and 89.1% RBL vs. 78.7% SCL, RR 1.17, 95% CI 1.02-1.34, respectively). Both techniques had similar results in terms of pain relief, overall control of symptoms, and risk of recurrence at 3 months. Although patient satisfaction was significantly higher with RBL (77.8% RBL vs. 46.7% sclerotherapy, RR 1.59, 95% CI 1.01-2.50), post-procedural pain was significantly higher with this technique (24% RBL vs. 14% sclerotherapy, RR 1.74, 95% CI 1.32-2.28). There was no significant difference regarding post-procedure bleeding (11.1% RBL vs. 8.7% sclerotherapy, RR 1.29, 95% CI 0.86-1.94). In the subgroup analysis, according to the HD grade, post-procedure pain was higher with RBL only in HD grade II (vs. HD grade I-III). Conclusions: RBL performs better than sclerotherapy in controlling HD symptoms, specifically prolapse and bleeding, although post-procedural pain is a frequent complication. Recurrence is similar with both procedures. While waiting for the publication of results with sclerotherapy with new sclerosants, RBL remains the office-based treatment of choice in HD.

Contexto/Objetivos: Os tratamentos instrumentais mais frequentemente realizados na doença hemorroidária (DH) são a laqueação elástica (LE) e a escleroterapia. Existem poucos estudos publicados que comparem os vários tipos de tratamento instrumental. O objetivo desta revisão sistemática e meta-análise foi comparar a eficácia e a segurança da escleroterapia e da LE. Métodos: A pesquisa foi feita em três bases de dados. A eficácia (controlo dos sintomas, do prolapso, da hemorragia e da dor, satisfação dos doentes e recorrência da DH) e a segurança (complicações, tais como dor e hemorragia) foram os resultados avaliados. Os riscos relativos (RR) foram calculados para cada resultado, com recurso a um modelo de efeitos aleatórios, e a heterogeneidade foi avaliada pelo teste Q de Cochran e I2. Resultados: Foram incluídos seis estudos clínicos randomizados e três estudos de coorte. O controlo do prolapso e da hemorragia foi significativamente mais elevado com a LE (93,1% LE VS 66,4% escleroterapia, RR 1,34, 95% CI 1,12-1,60 e 89,1% LE VS 78,7% escleroterapia, RR 1,17, 95% CI 1,02-1,34, respetivamente). Ambas as técnicas tiveram resultados semelhantes em termos de alívio da dor, controlo global dos sintomas e risco de recidiva aos 3 meses. Embora a satisfação dos doentes fosse significativamente maior com LE (77,8% LE VS 46,7% escleroterapia, RR 1,59 95% CI 1,01-2,50), a dor pós-procedimento foi significativamente maior com esta técnica (24% LE VS 14% escleroterapia, RR 1,74, 95% CI 1,32-2,28). Não houve diferença significativa na hemorragia pós-procedimento (11,1% LE VS 8,7% escleroterapia, RR 1,29, 95% CI 0,86-1,94). Na análise de subgrupos, de acordo com o grau da DH, a dor pós-procedimento foi mais elevada com a LE apenas na DH grau II (VS DH graus I-III). Conclusões: A LE tem melhores resultados do que a escleroterapia no controlo dos sintomas, mais concretamente na resolução do prolapso e da hemorragia hemorroidária, embora a dor pós-procedimento seja uma complicação mais frequente com a LE. A recorrência é semelhante em ambos os procedimentos. Enquanto se aguarda a publicação dos resultados de estudos com novos esclerosantes, a LE deverá ser considerado o tratamento instrumental de primeira linha na DH.

Effectiveness and predictors of response to somatostatin analogues in patients with gastrointestinal angiodysplasias: a systematic review and individual patient data meta-analysis.

BACKGROUND: Gastrointestinal angiodysplasias are vascular malformations that often cause red blood cell transfusion-dependent anaemia. Several studies suggest that somatostatin analogues might decrease rebleeding rates, but the true effect size is unknown. We therefore aimed to investigate the efficacy of somatostatin analogues on red blood cell transfusion requirements of patients with gastrointestinal angiodysplasias and to identify subgroups that might benefit the most from somatostatin analogue therapy. METHODS: We did a systematic review and individual patient data meta-analysis. We searched MEDLINE, Embase, and Cochrane on Jan 15, 2016, with an updated search on April 25, 2021. All published randomised controlled trials and cohort studies that reported on somatostatin analogue therapy in patients with gastrointestinal angiodysplasias were eligible for screening. We excluded studies without original patient data, single case reports, small case series (ie, <10 participants), studies in which patients had a specific aetiology of gastrointestinal angiodysplasias, and studies in which somatostatin analogue therapy was initiated simultaneously with other treatment modalities. Authors of eligible studies were invited to share individual patient data. Aggregated data was used if individual patient data were not provided. The primary outcome was the mean reduction in the number of red blood cell transfusions during somatostatin analogue therapy, compared with baseline, expressed as the incidence rate ratio (IRR) and absolute mean decrease. We defined patients as either good responders (≥50% reduction in the number of red blood cell transfusions) or poor responders (<50% reduction). A mixed-effects negative binomial regression was used to account for clustering of patients and skewness in data. This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO), number CRD42020213985. FINDINGS: We identified 11 eligible studies (one randomised controlled trial and ten cohort studies) of moderate-to-high quality and obtained individual patient data from the authors of nine (82%) studies. The remaining two (18%) studies provided sufficient information in the published manuscript to extract individual patient data. In total, we analysed data from 212 patients. Somatostatin analogues reduced the number of red blood cell transfusions with an IRR of 0·18 (95% CI 0·14-0·24; p<0·0001) during a median treatment duration of 12 months (IQR 6·0-12·0) and follow-up period of 12 months (12·0-12·0), correlating with a mean absolute decrease in the number of red blood cell transfusions from 12·8 (95% CI 10·4-15·8) during baseline to 2·3 (1·9-2·9) during follow-up-ie, a reduction of 10·5 red blood cell transfusions (p<0·0001). 177 (83%) of 212 patients had a good response to somatostatin analogue therapy (defined as at least a 50% reduction in the number of red blood cell transfusions). Heterogeneity across studies was moderate (I2=53%; p=0·02). Location of gastrointestinal angiodysplasias in the stomach compared with angiodysplasias in the small bowel and colon (IRR interaction 1·92 [95% CI 1·13-3·26]; p=0·02) was associated with worse treatment response. Octreotide was associated with a better treatment response than lanreotide therapy (IRR interaction 2·13 [95% CI 1·12-4·04]; p=0·02). The certainty of evidence was high for the randomised controlled trial and low for the ten cohort studies. Adverse events occurred in 38 (18%) of 212 patients receiving somatostatin analogue therapy, with ten (5%) discontinuing this therapy because of adverse events. The most common adverse events were loose stools (seven [3%] of 212), cholelithiasis (five [2%]), flatulence (four [2%]), and administration site reactions (erythema, five [2%]). INTERPRETATION: Somatostatin analogue therapy is safe and effective in most patients with red blood cell transfusion-dependent bleeding due to gastrointestinal angiodysplasias. Somatostatin analogue therapy is more effective in patients with angiodysplasias located in the small bowel and colon, and octreotide therapy seems to be more effective than lanreotide therapy.

Portuguese Society of Gastroenterology Consensus on the Diagnosis and Management of Hemorrhoidal Disease.

Hemorrhoidal disease (HD) is a frequent health problem with considerable repercussions on patients' quality of life. However, much of the clinical practice related to HD is based on knowledge without scientific evidence and supported largely by empirical experience of the physician who deals with this pathology. As in other countries, the goal of this consensus is to establish statements supported by solid scientific evidence and whose purpose will be to standardize and guide the diagnosis and management of HD both in the general population and in some particular groups of patients.

A doença hemorroidária é uma patologia prevalente com repercussões consideráveis na qualidade de vida dos doentes. No entanto, muita da prática clínica relacionada com a doença hemorroidária é baseada em conhecimentos sem evidência científica e apoiada largamente por uma experiência empírica por parte do médico que lida com esta patologia. À semelhança do que tem sido feito noutros países, o objetivo deste consenso foi estabelecer statements suportados por evidência científica sólida e cuja finalidade será o de uniformizar e orientar o diagnóstico e tratamento da doença hemorroidária quer na população em geral quer em grupos particulares de doentes.

Cabergoline reduces the early onset of ovarian hyperstimulation syndrome: a prospective randomized study.

Prophylactic use of cabergoline has been associated with a decrease in the severity of ovarian hyperstimulation syndrome (OHSS). A prospective randomized study was designed to evaluate the potential of cabergoline to decrease the incidence of OHSS in high-risk patients undergoing assisted reproductive technology treatment; 166 patients with oestradiol concentrations over 4000 pg/ml on the day of human chorionic gonadotrophin (HCG) administration were evaluated. They all received 20 g routine preventive intravenous human albumin on the day of oocyte retrieval. They were then randomized into two groups: group A (n = 83) received 0.5 mg oral cabergoline per day for 3 weeks beginning on the day after oocyte retrieval, and group B (n = 83) received no medication. 'Early' OHSS was defined as being when the onset of the syndrome was initiated during the first 9 days after HCG administration, and 'late' OHSS was defined as being when the onset of the syndrome was initiated from 10 days after HCG administration. In group A, no patients progressed to 'early' OHSS and nine patients (10.8%) developed 'late' OHSS; in group B, 12 patients (15.0%) progressed to 'early' OHSS and three (3.8%) to 'late' OHSS. Although the risk of 'early' OHSS decreased significantly (P < 0.001), the risk of 'late' onset OHSS did not. The two groups presented no changes in pregnancy, implantation or miscarriages rates.

[Portuguese Consensus on the Diagnosis, Prevention and Treatment of Anaemia in Inflammatory Bowel Disease]. / Consenso Português sobre o Diagnóstico, Prevenção e Tratamento da Anemia na Doença Inflamatória Intestinal.

INTRODUCTION: Anaemia can be considered the most common extra-intestinal manifestation in inflammatory bowel disease. Nevertheless, anaemia is often under-diagnosed and under-treated both in adults and children with inflammatory bowel disease. Herein, we report the consensus statements on the management of anaemia in inflammatory bowel disease developed by the Portuguese Working Group on Inflammatory Bowel Disease (known as Grupo de Estudo da Doença Inflamatória Intestinal - GEDII) to aid clinicians in daily management of inflammatory bowel disease patients. MATERIAL AND METHODS: A comprehensive literature review was conducted in order to prepare consensus statements on the following topics: (1) prevalence and diagnosis of anaemia in inflammatory bowel disease, (2) iron supplementation for the prevention of anaemia in inflammatory bowel disease and (3) treatment of anaemia in inflammatory bowel disease. The final statements for each topic were discussed at a consensus meeting and rated according to the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence. CONSENSUS: It was concluded that anaemia has a high incidence and prevalence in inflammatory bowel disease, particularly in those with active disease and hospitalised. Patients with anaemia had decreased quality of life and frequently complained of fatigue. Absolute indications for intravenous therapy should be considered: (1) moderate to severe anaemia (haemoglobin < 10.5 g/dL) or clearly symptomatic anaemia; (2) previous intolerance to oral iron supplements; (3) inappropriate response to oral iron; (4) active severe intestinal disease; (5) need for a quick therapeutic response (e.g. surgery in the short term); (6) concomitant therapy with erythropoiesis-stimulating agent; and (7) patient's preference.

Introdução: A anemia pode ser considerada a manifestação extra-intestinal mais comum na doença inflamatória intestinal. Ainda assim, a anemia é subdiagnosticada e subtratada tanto em adultos como em crianças com doença inflamatória intestinal. Assim, apresentamos o consenso alcançado pelo Grupo de Estudo da Doença Inflamatória Intestinal - GEDII relativamente à gestão da anemia na doença inflamatória intestinal, com o objetivo de facilitar o acompanhamento clínico dos doentes com doença inflamatória intestinal. Material e Métodos: Foi conduzida uma revisão exaustiva da literatura, por forma a preparar statements de consenso nos seguintes tópicos: (1) prevalência e diagnóstico de anemia na doença inflamatória intestinal, (2) ferro da prevenção da anemia na doença inflamatória intestinal e (3) tratamento da anemia na doença inflamatória intestinal. Os statements finais para cada tópico foram discutidos na reunião de consenso e classificados de acordo com os níveis de evidência definidos em 2011 pelo Oxford Centre for Evidence-Based Medicine. Consensos: Concluiu-se que a anemia tem elevada incidência e prevalência na doença inflamatória intestinal, particularmente entre pacientes com doença ativa e hospitalizados. Indicações absolutas para terapia intravenosa devem ser consideradas quando existe: (1) anemia moderada a severa (hemoglobina < 10,5 g/dL) ou anemia claramente sintomática; (2) intoler'ncia prévia à terapêutica com ferro por via oral; (3) resposta inadequada à terapêutica com ferro por via oral; (4) doença intestinal ativa severa; (5) necessidade de resposta terapêutica rápida (e.g. cirurgia a curto prazo); (6) terapêutica concomitante com agente estimulante da eritropoiese; e (7) preferência do paciente.

Estudo comparativo entre técnicas manuais aplicadas em lutadores de jiu-jitsu com dor lombar / Comparative study among manual applied techniques in jiu-jitsu athletes with low back pain

O objetivo geral da pesquisa foi comparar a eficácia da aplicação de métodos fisioterapêuticos clássicos com a eficácia de técnicas manuais osteopáticas e quiropráticas, em casos de lombalgia aguda em atletas de jiu-jitsu. Foram estudados 60 atletas portadores de lombalgia aguda, que foram divididos em três grupos de 20 pacientes, sendo submetido, cada grupo, a apenas uma das terapias estudadas. As técnicas estatísticas utilizadas foram: o teste t de Student para comparação intragrupos e o teste ANOVA combinado ao teste de Tukey, para comparação intergrupos. Na primeira comparação, nos três grupos (p = 0,000) foi evidenciada melhora da dor lombar após tratamento. O teste ANOVA (p = 0,000) indicou diferença estatisticamente significativa entre os três grupos. O teste de Tukey apontou diferença estatisticamente significativa entre o grupo de fisioterapia clássica e os grupos de osteopatia e quiropraxia. As médias dos valores encontrados no pós-teste da escala analógica (que mediu a intensidade da lombalgia após cada tratamento) foram: fisioterapia clássica: 2,6; osteopatia: 1,9 e quiropraxia: 1,25. Concluiu-se, portanto, que o método mais eficaz no tratamento da lombalgia aguda em atletas de jiu-jitsu foi a quiropraxia, seguida pela osteopatia e pela fisioterapia clássica.

The aim of this study was to compare the effectiveness of the application of classic physical therapy methods and the osteopathic and chiropractic manual techniques in jiu-jitsu athletes with acute low back pain. We studied 60 athletes with acute low back pain, divided in three groups of 20 patients. They were submitted, either to osteopathic or chiropratic manual technique or classic physical therapy. The results were evaluated by the student test t for the intragroups study and the ANOVA test combined with the Tukey test, for comparison intergroups. All the groups should (p = 0,000) improvement of the lumbar pain. The ANOVA test (p = 0,000) indicated no significant difference among the three groups. The Tukey test pointed out significant difference between the group of classic physical therapy and the osteopathic and chiropractic groups. The average values observed in the post-test of the analogical scale (that measured the intensity of the low back pain after each treatment) were: classic physical therapy: 2,6; osteopathy: 1,9 and chiropractic: 1,25. In conclusion the most effective method in the treatment of the acute low back pain in jiu-jitsu athletes was the chiropractic manual technique. Though, osteopathic manual technique and classical physical therapy were also efficient on back pain rehabilitation.
